Reliable Biological Treatment with Fixed Film Reactors

What are Fixed Film Reactors (FFR)?

Fixed Film Reactors (FFR), also known as attached biofilm reactors, supports the growth of beneficial microorganisms to break down pollutants. Wastewater is sprayed onto the media to grow the desired bacteria that consume pollutants.

How Fixed Film Reactors Improve Wastewater Treatment

High Treatment Efficiency

Biofilm grows on media surfaces, providing a large active area for pollutant degradation

 

Compact Design

Requires less space compared to traditional suspended-growth systems like activated sludge

 

Stable Operation

Biofilm protects microbes from shocks and fluctations in flow or load

 

Effective Nutrient Removal

Supports nitrification and denitrification processes for nitrogen control

 

Low Sludge Production

Produces less excess sludge, reducing handling and disposal costs

 

Adaptable to Various Wastewater Types

Suitable for municipal, industrial, and decentralized treatment

 

Energy Efficient

Often requires less aeration and lower operational costs than conventional systems

Benefits of Fixed Film Reactors

Fixed Film Reactors offer exceptional versatility, ideal for treating both domestic and industrial wastewater. They can operate efficiently under aerobic, anoxic, or anaerobic conditions, making them adaptable to a wide range of treatment needs. With lower energy consumption compared to other technologies, they also provide a more sustainable, cost-effective solution for long-term performance. 

Applications of Fixed Film Reactors in Wastewater Treatment

Food and Beverage

Applied for treating high-strength or variable load wastewater.

 

Municipal Wastewater

Used in small to mid-sized treatment plants for stable BOD and ammonia removal, especially where space or operator resources are limited.

 

Resorts and Campgrounds

Provides consistent, compact treatment for facilities with fluctuating occupancy and limited infrastructure.

 

Wineries

Handles organic-rich effluents from seasonal operations with minimal operator oversight.
